. In Austria January 3, 1934 1 Claim.

Umbrellas are known, the frame of which consists of a plurality of wireswhich at the same time form the handle and which are opened byseparately bending down each roof rod and hooking it into thecorresponding spreading rod.

This procedure is complicated and takes time. According to the inventionthe roof rods are connected with strings which extend through theinterior of the stick so that all strings can be pulled by a handle toopen the umbrella.

An embodiment of the invention is illustrated by way of example in theaccompanying drawing in which:

Fig. 1 shows the umbrella in open condition.

Fig. 2 is a bottom plan view of Fig. 1.

Fig. 3 is a top plan view of the folded umbrella.

Fig. 4 shows the umbrella in closed condition in elevation.

Fig. 5 shows the umbrella in rolled condition.

Fig. 6 shows the locking device.

Figs. 7 and 8 show the fixation of the roof to the roof rods.

The umbrella frame is composed of four cane rods a of semi-circularcross-section, the lower portions of which surround a perforated woodencore to which they are connected so that they form both the roof rodsand also the stick.

The free ends of the cane rods forming the roof rods are connected withstrings b. These strings extend through holes i into the interior of thestick where they are united by a knot g. A string surrounding this knotleads to a ball at which forms the handle. The four strings I) are eachfixed at their upper end to one of the roof rods (1, extend through thecane bars 1 which support the cover, and are conducted towards themiddle below the roof and threaded through four holes 1' into the roofrods. The umbrella is opened by pulling the ball d. To maintain theumbrella in open position, a locking device is fitted on the lower endof the four cane rods a. This locking device consists of a spring ewhich, when the string is pulled downwards, is pushed aside and on thestring being released clamps the knot g against the cane bars a, therebypreventing the roof rods a which are under tension from returning intotheir initial position. To obtain a roof slightly sloping from themiddle to the edge four thin cane bars 1 are provided which are securedat the upper end of each cane bar a with 10 the paper or fabric cover 0by the string b. The more the cane rods a are bent by pulling thestrings b, the further the cane bars move in the opposite direction andthus press the roof upwards in the middle. A' more simple form ofconstruction consists in placing the round portion of the four cane rodsa inwards thereby producing a hollow space so that the wooden core 77.may be omitted.

When it is desired to close the umbrella, it is only necessary to pressaside the spring 6, whereby the knot g of the strings b moves into thehollow space of the four cane rods 0!. and the ball d bears against theopening of the cane rods a, the tension of the rods and of the cover 0being thereby relieved. In rolled condition the cover a is rolled aroundthe four cane rods a so that then the umbrella has the appearance of astick (Fig. 5).

I claim:-

An umbrella, comprising in combination four cane rods forming a hollowstick and at their upper ends flexible roof'rods, strings, severallyconnected at one end witheach of said cane rods and extending throughthe hollow stick and interconnected at their other end, and a pullmember connected to the united strings and adapted to spread said rodswhen pulled.
